I'm trying to use a checkbox in a nested ListView, and I'm having
trouble updating the selection.
I tried the wrapper example in the wiki but it didn't work:
http://www.wicket-wiki.org.uk/wiki/index.php/Listview_with_checkboxes_in_a_form
I'm using wicket 1.2 from february.
Any suggestions?
My code:
ListView searchList = new ListView("rows", new PropertyModel(this,
"searchResult")) {
public void populateItem(final ListItem listItem) {
final Party party = (Party) listItem.getModelObject();
listItem.add(new Label("id", Long.toString(party.getId())));
listItem.add(new Label("firstname", party.getFirstname()));
listItem.add(new Label("lastname", party.getLastname()));
List wrappedPcms = new ArrayList();
for (PartyContactMechanism pcm :
party.getPartyContactMechanisms()) {
wrappedPcms.add(new SelectionWrapper(pcm));
}
// Just create a new table, which will be put into the
current cell
listItem.add(new ListView("contact", wrappedPcms) {
public void populateItem(final ListItem listItem) {
final SelectionWrapper pcm =
(SelectionWrapper) listItem.getModelObject();
listItem.add(new Label("value",
pcm.getPartyContactMechanism().getContactMechanism().getContactMechanismType().getName()));
listItem.add(new CheckBox("selected", new
PropertyModel(listItem.getModel(), "selected")));
}
});
}
};
Form resultForm = new Form("resultForm");
resultForm.add(new Button("add") {
protected void onSubmit() {
System.out.println(getForm().getModelObject());
}
});
resultForm.add (searchList);
add(resultForm);
Where searchList is collection of Party-objects.
The SelectionWrapper:
private class SelectionWrapper implements Serializable {
private PartyContactMechanism pcm;
private Boolean selected = Boolean.FALSE;
public SelectionWrapper(PartyContactMechanism pcm) {
this.pcm = pcm;
}
public Boolean getSelected() {
return selected;
}
public void setSelected(Boolean selected) {
this.selected = selected;
}
public PartyContactMechanism getPartyContactMechanism() {
return pcm;
}
public void setPartyContactMechanism(PartyContactMechanism pcm) {
this.pcm = pcm;
}
public String toString() {
return pcm.getId() + ": " + selected;
}
}
